Protan Cool Roofs

Protan Cool Roof is a system that uses a white membrane with a documented high solar reflectance index (SRI) – and less need for cooling.

High solar reflectance – less need for cooling

A white roof surface with high solar reflectance produces a much lower temperature in a compact roof structure than darker colours. A high solar reflectance index makes the roof more durable, reduces the need for the building to be cooled and counteracts the urban heat island effect, an important factor in a Southern European climate.

In a cool climate it may be beneficial to lay white membrane in front of the fresh air intake of air conditioning units, for example, as the temperature will be several degrees colder than on the rest of the surface.

Protan Cool Roof

Protan Cool Roof is a roof system where a white membrane is used when laying exposed roofing with a documented high Solar Reflectance Index. It also has high thermal emissions, which is a measurement of how efficiently heat is radiated as thermal radiation to the surroundings.
